    • Transformation of a Boys Surface into a Steiners Surface and torus eversion 

      Langer, M. (Eurographics Association, 2003)
      The part 1 of the video shows a Boy s surface and a Steiner s Roman surface which are difficult to visualize without computer 3d graphics and demonstrates a continuous topological transformation between them. The part 2 ...

    • Experimenting Prioritized IK for Motion Editing 

      Boulic, Ronan; Le Callennec, Benoît; Herren, Martin; Bay, Herbert (Eurographics Association, 2003)
      The presented work illustrates the potential of an IK algorithm enforcing priorities among constraints for motion editing. Motion capture is a very efficient technique to deliver believable motions but usually most of the ...

    • DStrips: Dynamic Triangle Strips for Real-Time Mesh Simplification and Rendering 

      Shafae, Michael; Pajarola, Renato (Eurographics Association, 2003)
      Multiresolution modelling techniques are important to cope with the increasingly complex polygonal models available today such as high-resolution isosurfaces, large terrains, and complex digitized shapes 10. Large triangle ...

    • A Framework for Video-based and Hardware-Accelerated Remote 3D-Visualization 

      Goetz, Frank; Domik, Gitta (Eurographics Association, 2003)
      This paper presents a framework for video-based and hardware-accelerated remote 3d-visualization that produces and delivers high quality video streams at an accurate frame rate. The framework is based on the portable ...

    • Continuous Local Parameterization of Polygons 

      Maillot, Jerome (Eurographics Association, 2003)
      Texture mapping has now become a standard technique for adding visual details to 3d models. Nevertheless, intuitive mapping tools have made little progress in the past decade, compared to other computer graphics areas: ...

    • Automatic High Level Avatar Guidance Based on Affordance of Movement 

      Michael, Despina; Chrysanthou, Yiorgos (Eurographics Association, 2003)
      As virtual cities become ever more common and more extensive, the need to populate them with virtual pedestrians grows. One of the problems to be resolved for the virtual population is the behaviour simulation. Currently ...

    • Interactive Dynamic Environments Using Image-Based Modeling and Rendering 

      Davis, Timothy A.; Ficklin, Stephen P. (Eurographics Association, 2003)
      This paper presents a method for rendering a dynamic virtual environment using IBMR at interactive rates. Most IBMR methods are designed for use with static scenes and are awkward when extended temporally due to excessive ...

    • Animatope: A Manga-Styled Animation Expression Toolkit 

      Tohda, Asuka; Hasegawa, Sho; Inakage, Masa (Eurographics Association, 2003)
      Manga, a Japanese comic style, is becoming widely accepted within comic readers worldwide. In Manga, mimetic symbols and onomatopoeia symbols are heavily used to express emotions and various movements in a comic frame. In ...

    • Adaptive quantization with error bounds for compressed view-dependent multiresolution meshes 

      Grabner, Markus; Zach, Christopher (Eurographics Association, 2003)
      We present a simple method to adaptively determine compression parameters according to the given input data. Our method allows to make better use of the available dynamic range (number of bits per component of vertex ...

    • Mobile Augmented Reality for Environmental Management (MARE) 

      Danado, Jose; Dias, Eduardo; Romao, Teresa; Correia, Nuno; Trabuco, Adelaide; Santos, Carlos; Araujo, David; Duarte, Pedro; Rebocho, Rui; Palmeiro, Jose; Serpa, Joao; Costa, Manuel; Camara, Antonio (Eurographics Association, 2003)
      Access to real-time data while in field observations is often a requested issue in environmental management. Additionally, it is easier to see that information spatially distributed where it makes sense, leveraging users ...

    • Beyond Image Quality Comparison 

      Bornik, Alexander; Cech, Peter; Ferko, Andrej; Perko, Roland (Eurographics Association, 2003)
      We solve the problem of quantitative measuring of image quality, beyond the widely used MSE (mean square error) or even visual comparison. We combine eight feature-based and perceptually-oriented image quality metrics. The ...

    • Improved Indirect Photon Mapping withWeighted Importance Sampling 

      Szirmay-Kalos, Laszlo; Szecsi, Laszl (Eurographics Association, 2003)
      This paper offers a novel approach to the indirect photon mapping method. The placement of photons acting as virtual light sources is regarded as a cheap sampling scheme, allowing for the reuse of a complete shooting path ...

    • Shadow Mapping Based on Dual Depth Layers 

      Weiskopf, Daniel; Ertl, Thomas (Eurographics Association, 2003)
      Shadow maps are a widely used means for the generation of shadows although they exhibit aliasing artifacts and problems of numerical precision. In this paper we extend the concept of a single shadow map by introducing dual ...
